Features

Supports Linux, Mac OS X, BSD and Windows (Cygwin)!
- If the script doesn't work on your system, open an issue.
It's Fast
- The script makes heavy use of bash builtins and string manipulation.
Display an image next to the info.
- Use your current wallpaper, shuffle through a directory or just display an image of your choice.
- Supports using w3m or iTerm2 to display the images.
Display ascii next to the info.
- Use a file containing ascii art as the image.
Highly Customizable
- You can customize almost everything.
  - See Usage below or lines 23-233 in script
Take a screenshot at the end.
- It's disabled by default and you can specify the cmd to use with --scrotcmd cmd at launch or by changing the value of $scrotcmd in the script.

Dependencies

Required dependencies:

All OS:

Bash 4.0+

Uptime detection: procps or procps-ng

Optional dependencies:

NOTE: If w3m or Imagemagick aren't found then image support will be disabled.

All OS:

Displaying Images: w3m
- You may also need w3m-img
- Note: The script can now also use iTerm2's builtin image rendering instead of w3m! Enable it by changing $image_backend to iterm2 or by using the launch flag --image_backend.
Image Cropping, Resizing etc: ImageMagick
More accurate window manager detection: wmctrl

Linux / BSD:

Display Wallpaper: feh, nitrogen or gsettings

- You can change this to another program with a --scrot_cmd and an in script option.

Installation

Arch

Install fetch-git from the aur.

Others

Download the latest source at https://github.com/dylanaraps/fetch
Make the file executable using chmod. chmod +x /path/to/fetch
Move the script to somewhere in your $PATH or just run it from where it is.

Post Install

Sizing the image correctly

NOTE: For the images to be sized correctly you need to set the $font_width variable. If you don't know your font width in pixels keep trying values until the image is sized correctly.

You can also use the launch flag --font_width to set it on the fly.

Customizing what info gets displayed

At the top of the script there's a function that allows you to customize all of the info that gets displayed.

Here's what you can do:

Add new info lines
Change the ordering of the info
Remove unwanted info lines
Use bash syntax to control when info gets displayed

See this wiki page that goes more in-depth about it:

https://github.com/dylanaraps/fetch/wiki/Customizing-Info

Customizing the script using a custom alias

If you don't want to edit the script you can customize almost everything using launch flags!

Here's what my fetch alias looks like:

alias fetch2="fetch \
--block_range 1 8 \
--line_wrap off \
--bold off \
--uptime_shorthand on \
--gtk_shorthand on \
--colors 4 1 8 8 8 7 \

Frequently Asked Questions

Why doesn't fetch support my wallpaper setter?

It's hard to add support for other wallpaper setters as they don't provide a way of getting the current wallpaper from the cli.

If your wallpaper setter does provide a way of getting the current wallpaper or you know where it's stored then adding support won't be a problem!

Issues and Workarounds

fetch: line 1655: /usr/lib/w3m/w3mimgdisplay: No such file or directory

You're getting this error because the script can't find w3mimgdisplay in it's default location. You can fix this by setting the config option $w3m_img_path to the correct location of w3mimgdisplay.

Other places that w3mimgdisplay could located be are:

/usr/lib/w3m/w3mimgdisplay
/usr/libexec/w3m/w3mimgdisplay
/usr/lib64/w3m/w3mimgdisplay
/usr/libexec64/w3m/w3mimgdisplay

The image is blank and won't show up.

If the images display in ranger and w3m then it's an issue with my script and not your terminal emulator.

Some terminal emulators don't support viewing images with w3m. You can either disable images with --image off at launch or image=off inside the script.

The image is rendering with black lines in Urxvt while using an xft font.

This is an issue with w3mimgdisplay and not the script. You can find a possible workaround here:

https://github.com/hut/ranger/issues/86#issuecomment-17346249

The text is too long for my terminal window and wraps to the next line causing the image to not render correctly.

There are a few ways to fix this.

Disable line wrapping with line_wrap=off in the script or with the launch flag --line_wrap off
The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can enable them by changing these variables or using these flags.

# In script options
uptime_shorthand="on"
gtk_shorthand="on"
gpu_shorthand="on"

# Launch flags
--uptime_shorthand on
--gtk_shorthand on
--gpu_shorthand on

Edit the info array to make the subtitles shorter
Resizing the terminal so that the lines don't wrap.

The text is pushed over too far to the right

The easiest way to fix this is to change the value of --gap or $gap to a negative value. For example --gap -10 will move the text 10 spaces to the left.

getgpu doesn't show my exact video card name

If your lspci | grep "VGA" output looks like this:

01:00.0 VGA compatible controller: NVIDIA Corporation Device 1401 (rev a1)

Instead of this:

01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1)

Then you're affected by the issue.

This is caused by your /usr/share/misc/pci.ids\* files being outdated and you can fix it by running this command as root.

sudo update-pciids
